I don;t know if you can tell from puffball pictures with out being feathered out yet. I've been looking all over at pics of chicks. I forgot to ask what kind of chicks I was getting the other day. I know the Cornish X ones. And the red are Sagittas. I've got three though that I'm not sure of. One is a yellow with a black spot on it's head and a black splot on it's back. The wing feathers are coming in white with one little black/white feather. The other two are yellows that looks like they rolled around in soot. Their under fluff is yellow and one has a darker grey-ish head. Their wing feathers are coming in white.
